SUNNYVALE, Calif. – Alpha and Omega Semiconductor Limited (AOS) introduced AOZ5131QI, the latest generation of power modules. The new device enables high power-density voltage regulator solutions ideal for CPU and GPU power regulation in notebook PCs, servers, and graphic cards.

The new AOZ5131QI integrates a dual gate driver and two optimized MOSFETs in a 31-pin 5mm x 5mm QFN package to produce a high power and high-efficiency power stage for synchronous step-down applications. The standard 5mm x 5mm QFN package is designed to provide maximum power density with low parasitic inductance and minimal EMI signature.

“The AOZ5131QI is the latest addition to our QFN5x5 standard package footprint series. By integrating FETs optimized for 12V input, the new device enables high efficiency and high-power density to satisfy the ever increasing customers' demand for higher performance in smaller and more power efficient products,” said Mehdy Khotan, Product Marketing Director for DrMOS product line at Alpha and Omega Semiconductor.
